Are they toxic?
Do they corrode in air?

The alloys in these magnets include rare-earth metals like samarium and neodymium. None of these metals is particularly toxic in metallic form, but some of their water-soluble salts are. And the alloys, as far as I know, either don't oxidise easily or they forn a thin protective oxide coat that prevents further corrosion, just like aluminium and stainless steel.

some are some aren't toxic, but you shouldn't eat them either way. most won't corrode in air, but it depends on the alloy used

Iron cobalt and nickle, geeze. These are the same feromagnetic materials found in the earth's core.

iron, cobalt, and nickel, (all in powder form), in a ceramic base.
In the finished product, they are not toxic, and neither do they corrode.

They are not corrosive neither are they toxic. Magnatite is the name of the material.

Iron(of course)
Nickel(:D-the ELEMENT not the COIN!)
A bit of chromium
toxic?(alone)-no,yes,maybe
corrode in air?(alone)-yes,?,no

neodymium-iron-boron (NdFeB) also known as rare earth, super strong
